AST Suspension 5200 Series Coilovers

The AST 5200 Series adds 2-way damping adjustment to AST's motorsport-grade platform, letting you tune bump and rebound independently. At Springrates we carry the 5200 Series for a wide range of applications.

2-Way Adjustable AST Coilovers

The 5200 Series takes AST's Dutch motorsport engineering and adds independent 2-way damping adjustment, so you can tune compression and rebound separately. That extra control lets you dial in body control and grip for specific tracks, surfaces, and tire packages, while keeping the superb ride quality AST is known for. Like all AST dampers, the 5200 is fully rebuildable and revalvable.

Where the 5200 Fits

Step up to the 5200 from the fixed-damping 5100 Series when you want the ability to fine-tune bump and rebound independently — ideal for a serious track-day or club-racing car. For the highest level of adjustment, the 5300 Series offers full 3-way control.

FAQs

What does 2-way adjustable mean on the AST 5200?

It means you can adjust compression (bump) and rebound damping independently, giving you finer control over body movement and grip than a single-adjustable kit. It's ideal for track and club-racing tuning.

What's the difference between the AST 5100 and 5200?

The 5100 has fixed (expertly valved) damping, while the 5200 adds independent 2-way adjustment of bump and rebound. Step up to the 5200 when you want to fine-tune the car for specific tracks and conditions.

Is the AST 5200 good for the street?

Yes. Despite its 2-way adjustability and motorsport pedigree, the 5200 retains AST's excellent ride quality, so it works on fast-road cars as well as track builds.

Can the AST 5200 be rebuilt?

Yes. Like all AST dampers, the 5200 Series is fully rebuildable and revalvable, so it can be serviced and re-tuned as your build evolves.

Should I get the 5200 or the 5300?

Choose the 5200 for independent 2-way (bump and rebound) adjustment. Step up to the 5300 if you want full 3-way control for the highest level of tuning on a serious race car.

Do I need an alignment after installing the AST 5200?

Yes. Any ride-height change alters camber and toe, so an alignment is required afterward — corner weighting is also worthwhile on a track build.
